Determination of benzene and alkylbenzenes in milk by purge and trap gas chromatography

Milk samples were analyzed for benzene and alkylbenzenes by a purge and trap gas Chromatographic method. Average concentration (n = 26) of benzene, toluene, ethylbenzene, m/p-xylene and o-xylene in human milk was 0.7, 12.8, 1.3, 4.7 and 1.4 ppb, respectively. These concentrations were found to be fr...

Summary:Milk samples were analyzed for benzene and alkylbenzenes by a purge and trap gas Chromatographic method. Average concentration (n = 26) of benzene, toluene, ethylbenzene, m/p-xylene and o-xylene in human milk was 0.7, 12.8, 1.3, 4.7 and 1.4 ppb, respectively. These concentrations were found to be from six to more than sixty times higher than results reported by other studies. These concentrations were also comparable to those found in cow's milk (n = 9). Correlation between pollutant concentrations in milk and urban air was demonstrated by comparison of the BTEX ratio, calculated from concentrations in different matrices.
